Although the price seems high. I can definitely say these are worth the purchase. They work very well; especially for going for PR’s 

Would not use anything else. Its effectiveness is fantastic and does not give you that jittery feeling or tiredness afterwards,which some products tend to do. Defo my go to pre-workout. Gives you that extra boost you need. Goes Well With: I don't mix it with anything as it is a shot,but it does not taste bad,so am sure you could blend it with ice-cubes and make a refreshing drink out of it.

For the price they are ok, knock it back in one and wait half an hour, gives you that extra energy to push whatever workout of your choice Goes Well With: Everything

The taste initially caught me off guard but after the first shot was absolutely fine. Effective product. 

Tastes nice, goes down easy and provides that boost of energy you want from a pre workout without any of the itchy tingles I've experienced with others
